I’m probably in the minority, but I’ll take slimmer, lighter and better sealed over user replaceable batteries. I’ve been using iPhones since changing from Androids to a iPhone 7, primarily because of getting tired of UIs changing constantly and not getting updates after a year or two. I know Samsung and Pixel phones do better with the updates now, but I think this would be more relevant to legislate about, instead of battery replacement.
I know it doesn’t sound as much, but it’s one example and it is still 1.5mm thicker than my iPhone and ip67 instead of ip68. If it turns out, I have nothing to worry about then great, but atm I know what I have and gain nothing from user replaceable batteries as I’ve never had a phone/iPad where I wanted to change the battery. Others may prefer differently.
